Abstract

"FILTROS DE CIGARRO DE ELEVADA EFICáCIA TENDO FIBRAS DE MICROCAVIDADES MODELADAS IMPREGNADAS COM MATERIAIS ADSORVENTES E ABSORVENTES". Esta invenção é um filtro altamente eficiente contendo fibras (22) que contém adsorventes / absorventes de tamanho de partícula pequena (23) tais como carbono e/ou sílica para seletivamente reduzir componentes alvejados em fumaça de cigarro de corrente principal. A invenção refere-se a uma nova classe de filtros de fumaça de cigarro altamente eficientes preparados de partículas finas muito menores (preferivelmente de 1 a 50 micrómetros em diâmetro) impregnadas em fibras modeladas (22) que possuem microcavidade aberta ou semi-aberta. A invenção também referese a um cigarro (10) tendo uma configuração de tampão / espaço / tampão (12, 14, 16) ou tampão / espaço (12, 14) e tendo os filtros impregnados resididos no espaço de maneira não trançada ligada ou livremente soltos desamarrados para permitir a liberação de TPM controlada."HIGH EFFICIENCY CIGARETTE FILTERS HAVING MODELED MICROCAVITY FIBERS IMPREGNATED WITH ADSORBENT AND ABSORBENT MATERIALS". This invention is a highly efficient fiber-containing filter (22) containing small particle size adsorbents / absorbers (23) such as carbon and / or silica to selectively reduce targeted components in mainstream cigarette smoke. The invention relates to a new class of highly efficient cigarette smoke filters prepared from much smaller fine particles (preferably from 1 to 50 micrometers in diameter) impregnated with shaped fibers (22) having open or semi-open microcavities. The invention also relates to a cigarette (10) having a tampon / space / tampon (12, 14, 16) or tampon / space (12, 14) configuration and having the non-braidedly impregnated space-resident impregnated filters untied loose to allow controlled TPM release.
